Authorities say police officers shot and killed three people in less than an hour in Kansas City, Missouri, raising concerns about police tactics.

The Kansas City Star reports that police killed two men who were fighting in a downtown public square, Thursday. The shooting happened after officers killed a woman seen brandishing a sword in a residential area about 10 miles (16 kilometers) away.

A nearby resident, Robert King, questioned why police who shot the women didn't use tear gas instead of a firearm.

The Rev. Vernon Howard, president of the Southern Christian Leadership Conference of Greater Kansas City, bemoaned the "fatality on top of fatality."

Kansas City Police Chief Rick Smith says the "incidents unfolded protecting other citizens."
